Brock Noland commented on HIVE-7799:
------------------------------------
When resolved me might consider adding
* orc_merge1.q
* orc_merge2.q
* orc_merge3.q
* orc_merge4.q
from HIVE-7792.
> TRANSFORM failed in transform_ppr1.q[Spark Branch]

> Basically, the cause is that RowContainer is misused(it's not allowed to

> hive issue or just in hive on spark mode.
